Hydrogeological condition in the Newaj Watershed using thematic layers generated by the spatial Data.

Abstract

The present study is an attempt to describe the hydrogeological condition of Newaj Watershed of Rajgarh District, Madhya Pradesh, by the themes generated using spatial data such as geology, geomorphology, lineament, drainage, and landuse / landcover maps. The geological map corealeted with field data show that the basic volcanic rocks present in the area have no primary porosity but because of weathering and due to presence of fractures and joints a secondary porosity has been developed which favours the movement and accumulation under the surface. Similarly presence of surface landform also favour the groundwater conditions as the landform like Pediplain, pediments and deeply weathered plateau seems primarily favourable site for groundwater percolation and accumulation. Lineaments density, drainage texture and present landuse/landcover also favour the groundwater movement and accumulation hence, the analysis of these themes give primary information regarding hydrological study which may be used before detailed investigations for groundwater.
